Personalizing Health Outcome in Epilepsy Now - An Introduction to Clinical Services

Potential subjects will be systematically approached during a 3 years enrollment period to recruit a consecutive sample of the patient population receiving care at a tertiary care epilepsy center (Toronto Western Hospital). After an 8 week period to establish baseline measurements the proposed trial will allocate study subjects to an A/R intervention group or a relaxation/meditation control group or a usual care control group (N1=N2=N3=10) per their preference due to the fact that internalization of the therapeutic principles is an active process that requires continuous motivation and compliance of the patient with the intervention. If a subject displays high intrinsic motivation to engage in self-care enhancing activities but does not indicate a preference, he or she will get randomized to either the A/R intervention or the relaxation protocol. This trial design allows for measuring effect sizes in regard the potential effect of choice, and also whether there is any interaction between preference and treatment. This trial will determine the following: I. The fraction of (a) seizure-free subjects and (b) subjects with clinically meaningful, i.e. ≥ 90% or ≥ 50 reduction of seizure frequency, II. Changes of the subjective perception of disability as indicated by Subjective Handicap of Epilepsy Scale (SHE), III. Changes of seizure self-efficacy as indicated by Multidimensional Health Locus of Control (M-HLOC), Form C and Epilepsy Self-Efficacy Scale (ESES), IV. Changes in common psychopathologic comorbidities and stress as indicated by (a) Neurological Disorders Depression Inventory in Epilepsy (NDDI-E), (b) State Trait Anxiety Inventory (STAI), (c) Profile of Mood States (POMS brief), and (d) Perceived Stress Scale (PSS), V. Changes in quality of life as indicated by (a) Quality of Life in Epilepsy (QOLIE-89), (b) individually identified descriptors of various domains of life and (c) individually identified epilepsy-related distresses. Continuous measures (aims I and III b) will be obtained during months 9 and 10 after initial subject enrollment. All other measures will be obtained at the end of month 10. Intervention Protocols: During months 3-5 the A/R intervention protocol devotes one face-to-face counseling session to each of the 11 chapters ("steps") of the workbook "Taking control of your epilepsy" which will be followed by weekly phone calls during months 6-8. A/R treatment plans include daily activities: Journaling (10 min), CD-guided relaxation (10-30 min), Workbook (10 min) to promote functional analysis of seizure context and development of coping strategies. The trial will be used for knowledge-translation as trainees delivering the intervention will be supervised by Donna Andrews, PhD, co-developer of the AR intervention. The relaxation and meditation protocol will consist of weekly 30 min session during months 3-5 and bi-weekly 60 min sessions during months 6-8. All subjects are instructed to document seizure occurrences (number and type) and compliance with AEDs. They will continue to see their treating neurologist and adjustment of their antiepileptic medication will be made if necessary. Medication changes will be included in outcome analyses. Regular serum levels will be drawn to monitor drug compliance. Study subjects will be approached at 12, 24 and 36 months after the end of the pilot trial to obtain follow-up data. The sample size determination the investigators based on literature review, assuming the remission rate for the usual care group was 5% and 35% for the A/R intervention group and inflated by 30% to account for loss to non-compliance. Outcomes will be compared as found in groups as a whole.
